Obvious garbage, but people should be skeptical of all polling that seems to go against fundamentals, not just those which show results that they don't like.
Except a Murphy +6 result is far more believable than this nonsense given the current environment and Democrats' national numbers (which everyone here seems to be ignoring, pretending that we’re still in 2017), so no, you don’t have to dismiss the Emerson poll just because you (understandably) dismiss the one.
A Murphy +
4 result might be *relatively* more believable than this poll, but that's a low bar. A 4-point result in NJ is not plausible barring a huge drop in popularity for Murphy or a 1980-style environment for Democrats. If this were 2017, I'd expect more like Murphy +20 instead of Murphy +10.
